“…This insect preference and best performance for grasses has been previously demonstrated by other researchers. S. frugiperda preferred grasses such as maize, sorghum, and bermudagrass, which are C 4 plants, as opposed to C 3 plants such as cotton or soybean (Buntin, 1986;Lewter et al, 2006;Nagoshi et al, 2007). This might be due to the composition and nutritional adequacy of these plants in relation to hosts from other botanical families (Pashley, 1986(Pashley, , 1988Barros et al, 2010) with the consequence that, ultimately, insect foraging is an exercise in acquiring the best blend and balance of suite nutrients, including amino acids, carbohydrates, sterols, phospholipids, fatty acids, vitamins, minerals, trace elements, and water (Behmer, 2009 , and inorganic phosphate from 20 to 60 50 mg dm −2 (Mondal et al, 1978).…”

We studied Spodoptera frugiperda development using different food sources in the laboratory and field. Newly hatched larvae were fed soybean, cotton, maize, wheat, and oat leaves. An artificial diet was used as the control. Duration of pre-pupal, pupal, and larva-adult period, pupal weight, sex ratio, survival, larva feeding preferences, oviposition preferences, and nutritional quality of different hosts were evaluated. Insects fed on wheat showed the shortest larva-adult period. The insects fed on cotton and soybean had longer larval development cycles and pupae of lower weight. Feeding preference was evident for third instar larvae and did not differ between wheat, oat, maize, and soybean, which were the preferred hosts. Moths oviposited to a greater extent on the upper canopy of wheat than that of other plants in both the no-choice and free-choice tests. Treatments influenced insect growth, food consumption, and digestion when nutritional variables were analyzed. Thus, grasses were better hosts for S. frugiperda development. Cotton was the least preferred food, followed by soybean. The present study can improve our understanding of S. frugiperda in these different crops and help in developing management strategies. Even though S. frugiperda is considered to be polyphagous, this pest is closely associated with grasses (maize, wheat, oat) and has lower potential as a soybean or cotton feeder. Howerver, S. frugiperda food intake regulation appears to be triggered by a complex of different mechanisms. Thus, S. frugiperda can also damage soybean and cotton and adapt to them in the absence of preferred hosts.

“…Sosa-Gómez (2004) also found high gene flow in Biochem Genet (2011) 49:760-787 761 A. gemmatalis, using random amplification of polymorphic DNA. Lewter et al (2006) evaluated the genetic structure of the migratory fall armyworm, S. frugiperda (J. E. Smith), across part of its range in America using mitochondrial COI and COII and the nuclear internal transcribed spacer 1 (ITS1) of ribosomal RNA; it was demonstrated that all individuals could be divided into three corn and four rice strain haplotypes. The range of genetic divergence between the two strains was 0.66-0.99% on the basis of the COI and COII genes, but no variation was detected by ITS1.…”

In an effort to gain greater insight into the nature of the population genetic structure of the pest insect Spodoptera litura (Lepidoptera: Noctuidae), tobacco cutworms were collected from six Korean and five Chinese localities, and their mitochondrial A+T-rich region and nuclear internal transcribed spacer 2 (ITS2) were cloned and sequenced. The A+T-rich region and nuclear ITS2 provided a maximum sequence divergence of 2.88 and 1.82%, respectively. Overall, a low level of genetic fixation (F(ST) = 0-0.02965 in the A+T-rich region and 0-0.34491 in ITS2) and no discernible isolated population were noted among most S. litura populations. Along with these results, the absence of genetic variance between Korea and China indicates a profound interrelation of the S. litura populations in the two countries, consistent with the current notion that S. litura has sufficient flight capacity for dispersal.

“…Estos resultados demuestran que los haplotipos de maíz y arroz de este país, se mueven dentro de cada uno de estos cultivos y por lo tanto muestran una asociación a su planta hospedera respectiva. Este mismo resultado fue obtenido por Lewter et al (2006) en un trabajo en el que analizaron 71 secuencias de S. frugiperda de Estados Unidos y en el que encontraron tres haplotipos exclusivos del cultivo de maíz y cuatro haplotipos exclusivos del cultivo de arroz. Los haplotipos identificados por estos últimos autores fueron utilizados en el presente trabajo para compararlos con los haplotipos de la misma especie en Colombia.…”

Approach to Spodoptera (Lepidoptera: Noctuidae) phylogeny based on the sequence of the cytocrhome oxydase I (COI) mitochondrial gene. The genus Spodoptera includes 30 species of moths considered important pests worldwide, with a great representation in the Western Hemisphere. In general, Noctuidae species have morphological similarities that have caused some difficulties for assertive species identification by conventional methods. The purpose of this work was to generate an approach to the genus phylogeny from several species of the genus Spodoptera and the species Bombyx mori as an out group, with the use of molecular tools. For this, a total of 102 S. frugiperda larvae were obtained at random in corn, cotton, rice, grass and sorghum, during late 2006 and early 2009, from Colombia. We took ADN samples from the larval posterior part and we analyzed a fragment of 451 base pairs of the mitochondrial gene cytochrome oxydase I (COI), to produce a maximum likelihood (ML) tree by using 62 sequences (29 Colombian haplotypes were used). Our results showed a great genetic differentiation (K2 distances) amongst S. frugiperda haplotypes from Colombia and the United States, condition supported by the estimators obtained for haplotype diversity and polymorphism. The obtained ML tree clustered most of the species with bootstrapping values from 73-99% in the interior branches; with low values also observed in some of the branches. In addition, this tree clustered two species of the Eastern hemisphere (S. littoralis and S. litura) and eight species of the Western hemisphere (S. androgea, S. dolichos, S. eridania, S. exigua, S. frugiperda, S. latifascia, S. ornithogalli and S. pulchella). In Colombia, S. frugiperda, S. ornithogalli and S. albula represent a group of species referred as "the Spodoptera complex" of cotton crops, and our work demonstrated that sequencing a fragment of the COI gene, allows researchers to differentiate the first two species, and thus it can be used as an alternative method to taxonomic keys based on morphology. Finally, the ML tree did not cluster S. frugiperda with S. ornithogalli, suggesting that both species do not share the same recent ancestral even though they coexist in cotton. We suggest sequencing other genes (mitochondrial and nuclear) to increase our understanding of this genus evolution. Rev. Biol. Trop. 60 (3):
